GEORGE G. F. BOSWELL, OF INDIANAPOLIS, INDIANA, ASSIGNOR OF ONE-FOURTH TO DAVID A. BOSWELL, 0F INDIANAPOLIS, INDIANA.

COIN-CONTROLLED LOCK.

To all whom it may concem:

Be it known that I, GEORGE G. F. Bos- WELL, a citizen of the United States, and a resident of Indianapolis, county of Marion, and State of Indiana, have invented a certain useful Coin-Controlled Lock; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings.

The object of this invention is to provide an improved coin controlled lock for use on doors of various sorts of booths and the like.

The chief features of the invention consists in providing a plate secured to the bolt of the lock for covering and uncovering the entrance to the coin chute, as the lock is operated, so that said entrance will be closed when the booth is occupied and the entrance will be open when the booth is unoccupied and also particular means for lodging and dislodging the coin in connection with the bolt for throwing the bolt.

The nature of the invention will be understood from the accompanying drawings and the following description and claims:

In the drawings, Figure 1 is a portion of a door with the lock installed thereon. Fig. 2 shows the lock on an enlarged scale with the parts in idle position and with the cover removed. Fig. 3 shows the same as Fig. 2, but with the bolt withdrawn and the coin slot closed. Fig. 4 is a vertical section on the line 41 of Fig. 2. Fig. shows the same after the parts have been operated and the coin allowed to fall through the slot. Fig. 6 is the same as Fig. 2, but showing the coin slot closed. Fig. 7 is a horizontal transverse section on the line 77 of Fig. 2. Fig. 8 is a horizontal transverse section on the line 8-8 of Fig. 6.

There is shown in the drawings a door 10 with a lock mounted thereon having a knob 11, bolt 12 and casing 13 having a small removable door 14 in the lower portion thereof allowing access to the interior of the casing and with a slot 18 in the upper portion thereof. Said casing 13 is secured to the back plate 15 by means of screws 16 extending through flanges 17 of the casing which lie behind the door 14:. The front knob 11 is mounted on the knob shaft 19 which has the bearings 20 in the frame 15 and in the front casing 13, as shown by Specification of Letters Patent.

dotted lines in Figs. 4 and 5. Said bearing portions are circular in cross section and between said bearing portions there is a portion which is square in cross section, see Figs. 2 and 3, with shoulders 120 thereon which bear against said casing and said back plate and prevent transverse movement of the knob shaft.

The portion of the knob shaft which projects beyond the casing is square in cross section to fit a corresponding hole in the shaft of the knob 11. Said knob 11 is secured to the knob shaft by means of a screw 21. Said knob shaft 19, located somewhat below the center of the casing and to one side, has an Lshaped arm 22 extending upwardly therefrom, substantially midway between the casing 13 and the frame 15 and in the outer end of the bent portion a pin 23 is secured against one end of which aspring 24L bears whose other end is rigidly secured by means of a screw 25 to one wall 26 of the coin chute 27, hereafter described. The action of the spring tends to maintain the knob shaft in the position shown in Fig. 2.

The bolt 12 has a beveled outer end common to most locks, is substantially rectangular in cross section and has a longitudinal slot 28 cut therethrough in a plane parallel with the door and midway of the bolt through which the arm 22 extends. Said slot 28 extends for substantially the entire length of the bolt within the casing and allows the free movement of the knob shaft 19 and the arm 22 thereon without imparting motion to the bolt 12 unless a coin has been dropped through the coin slot 18 in the casing. There is a second slot 29 through said bolt 12 at right angles to the slot 28 and extending transversely of the bolt to allow passage of the coin. There is a groove 30 in the vertical face of the bolt away from the door in which a projection 31 extends from a slot closing plate 32, hereafter described. A spring 34 secured between pins 35 in the frame 15 bears against the rear end of the bolt 12 and causes it to assume the position shown in Figs. 1 and 2, and a stop 33 extending outwardlyfrom the frame 15 governs the extreme outward movement of the bolt. There is a horizontal plate 36 extending transversely of the lock upon which the bolt 12 rides and lying immediately above the knob shaft 19.

The slot closing plate 32 is L-shaped in outline, as shown in Fig. 2, and near one end of the vertical leg there is a slot 37 which, when the plate is in the position shown in Fig. 2, will mate with the slot 18 in the casing 13 and allow a coin to be inserted therethrough and fall into the coin chute 27. Thei'e is a horizontal opening 42 cut in the lower portion of the slot closing plate 32 through which the guiding boss 38 extends from the bolt 12. The lower edge of said slot closing plate 32 rides on the horizontal guiding plate 36 and its outward motion and any escape from the bolt is prevented by a catch 39 secured to the frame by a screw 40. The rearwardly extending portion on the back side of said slot closing plate 32 lies immediately below the opening 42 and extends for substantially one half the length of the lower leg with the left end cut away to leave a V-shaped portion 43, as shown in Fig. 4, which will, when the plate 32 is in the position shown in Fig. 2, stop the downward motion of the coin through the slot 27. Said V-shaped portion 43 is inclined toward the horizontal opening 42 and lies below the coin slot in the upper leg of said L-shaped plate. The rearward extension 44 from the upper leg engages one wall of the coin slot 27 to limit the movement of said slot closing plate, as shown by dotted lines in Fig. 2.

The coin chute 27 is formed by outward extending plates 26 from the rear plate 15 extending downwardly from a point near the top of the casing and mating with the slot 18 in the cover thereof and extending downwardly toward the vertical slot 29 in the bolt 12.

The rear knob shaft 48 is somewhat similar to the front knob shaft 19 in that it has bearings in the casing 13 and plate 15 and has shouldered portions thereon to prevent the lateral motion of the shaft. There is a bar 49 extending at right angles to said knob shaft with one end extending downwardly through the vertical slot 28 in the bolt 12 and adapted to bear against the closed end of said slot and'cause the withdrawal of the bolt when the rear knob of shaft 48 is turned, and with the other end extending upwardly and adapted, when the rear knob shaft is turned, to bear against the projection 44 from the slot closing plate 32 and return the same to its normal position. Said knob shaft 48 extends through the front casing and is provided with a, key socket 50 into which a key may be inserted for causing the withdrawal of the bolt without depositing a coin in the coin slot.

When a coin is inserted in the slot 18 it will pass through the slot 37 in the slot closing plate 32 and fall through. the coin chute 27 and take the position shown in Fig. 4, where it lies against the rear wall of the bolt 12 and is supported by the V-shaped projection 43 on the plate 32. hen the front knob is turned the arm 22, on the knob shaft 19 extending through the slot 28 in the bolt 12, will bear against the coin and push the bolt to the right against the action of the spring 34, at the same time bearing against the projection 31 on the rear side of the plate 32 and cause it to move to the right also, whereupon the door may be opened, as shown in Fig. 3. hen the front knob is released, the spring 34 will cause the bolt to return to its normal posit-ion, shown in Fig. 3, but the coin will be returned to the position opposite the coin chute 27 and, passing from the V-shaped projection 43, will no longer be held upward thereby and will fall through the opening 51 in the plate 36 down to the lower portion of the casing. The turning of the rear knob shaft 48 will cause the bar 40 to assume the position shown by dotted lines in Fig. 2, and return the slot closing plate 32 to its normal position and at the same time withdraw the bolt and allow the door to be opened.

I claim as my invention 1. A coin controlled lock having a bolt, a stationary coin chute with a coin opening at one edge, a slidable plate having means thereon engaged by the coin when said bolt is withdrawn, whereby said plate will be moved into position to cover said coin chute and prevent the introduction of a coin, a spring to throw the bolt, and a knob controlled means to return said plate to a normal position and uncover said coin chute.

2. A coin controlled lock having a case, a coin chute in said case arranged to permit the coin to move downwardly crosswise of the case, a bolt having a transverse coin passageway through itwhich will register with the lower end of said coin chute when said bolt is thrown, a slidable plate having a projection thereon extending within said bolt which will catch and support the coin when it is within the bolt, means on said plate which will be engaged by the coin when said bolt is withdrawn and moves said plate into position to cover the coin chute, means for returning the bolt independently of said plate and dislodging the coin, and means actuated by a knob for returning said plate to a position for uncovering the-coin chute.

3. A coin controlled lock having a case, a coin chute in said case arranged to permit the coin to move downwardly crosswise of the case, a bolt having a transverse coin passageway through it registering with the lower end of said coin chute when .said bolt is thrown, a slidable chute closing plate having a projection thereon extending within a groove in said bolt and which will catch and support the coin when it is within said bolt, a shoulder on said projection which will be engaged by the coin when said bolt is withdrawn whereby said plate will be moved into position to cover the coin chute, a knob and shaft, the latter provided With an arm projecting through the bolt for engaging the coin When in the bolt and for Withdrawing the bolt When the knob is turned, a spring engaging the end of said arm for returning it to its normal position, means for return ing the bolt independently of said plate and dislodging the coin, and means actuated by the knob for returning said plate to a posi- 10 tion for uncovering the coin chute.
